Hydroforming

Hydroforming means forming an object with the aid of fluid subjected to high pressure. The process utilizes the fluid´s capacity to always press perpendicular to the material. Hydroforming can be used to form both tubes and flat panels (sheets). In both cases a forming tool is used which comprises an upper and lower forming section. These forming sections are held together by a hydroforming press HF. The part is formed by the pressure of the fluid against the inner sides of the forming tool. When running tube hydroforming, axial cylinders are added for sealing and inserting material. This method provides following unique benefits compared to conventional technology:

• Higher precision of the part
• Complex parts produced in one single tool
• Increased possibilities for product design
• Low weight due to reduced volume of material
• Higher structural strength of the part
• Less material thin-out
• Fewer operations
